WINDMILL.

Y SPECIFICATION forming' part of Letters Patent No. 256,154, dated April '11, 1882.

Application tiled September 28, 1881.

.To all lwhom it may concern:

Be it known that I, GEORGE W. MILLER, a. citizen ot' the United States, residing at Waterloo, in the county of Black Hawk and State of Iowa, have invented certain new and useful Improvements in Windmills; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure l of the drawings is aside elevation of my invention; and Fig. 2, a detail view, in perspective, ot a portion of the operating mechanism. A

The presentinvention relates to certain novel improvements in windmills; and it consists in the several details ot' construction, as will be hereinafter described, and subsequently pointed out in the claim.

In the accompanying drawings,Aisthe windwheel, and lthe rudder or vane, botll ot' which may be of metal or wood and of the usual construction.

The hollow standard C has adjustabiy connected to it a bracket, D, the latter having eyes a, throughwhieh passes the hollow standard, and to which is rigidly secured the shaft b of the rudder or vane, said bracket being held at the required position on the standard by a set-screw, c.

The turn-table E is connected to the standard C in any suitable manner that will admit of its Vturning horizontally to either the right or left, so as to bring the wheel A into the wind or action and regulate the saine during high winds or storms: The upper portion of this turn-table E forms a bearing for the shaft of the wheel A, and to the inner end of the shaft is keyed a disk, d. To this disk is eccentrically connected one end of a pitrnan, c, the other end being suitably connected to an operating-rod, f, which passes down through the hollow standard C, thereby giving to the rod f a verticallyreciprocating motion as the wind- (Model.)

stop, which might break it or cause strain upon the operating parts. This danger is prevented by the employment of the brake and pivoted lever for operating it, which brings the wheel to a gradual and easy stop.

The upper end of the rod f passes through a head, F, suitably connected to the end of the hollow standard G, said head havingV a pulley, t', over which passes a cord or rope, 7c. One end of this cord or rope is connected tomu pivoted lever, having secured thereon an adjustable weight, l,.while the other end of the cord or rope passes down through the hollow standard C in convenient reach of the attendant, who draws down upon it when it is desired to stop the wheel A, as will be presently described.

To the pivotal end of the lever G is rigidly connected a' segmental rack, H, the teeth ot' which engage with those of a similarly-formed rack, I, said rack being connected to or forming part o1" the turn-table E. As the cord orrope lc is pulled down the lever G will be raised, and the teeth of the rack G engaging with those of the rack I, it will bring the turn-table E around in the direction so as to cause the foot m to come in contact with the lever h and press it down, which will cause the brake'g to be drawn down tightly around the periphery of the disk d, thereby gradually stopping the wind-wheel without danger of injury to the operating parts.

It should be noticed that the lever G is pivoted to the bracket D, and the weight thereon is adjustable by a suitable set-screw, as is common in this class of windmill, and/therefore needs no further description.

Havingnow fully described my invention, what l claim as new, and desire to secure by Letters Patent, is

The turn-table E, supporting wheel A, disk d, brake y, pivoted lever lz, and the rack I, in combination with the bracket I), pivoted lever G, rack H, and cord or rope k, substantially as and for the purpose set forth.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

GEORGE W. MILLER.
